JD for Battery Management System (BMS) Architect
Responsibilities:
Architectural Design & Software Development:
- Lead the end-to-end design, development, and scaling of robust BMS software architectures for 2W, 3W, and high-voltage EV applications.
- Define software development best practices, MISRA-C/C++ coding standards, and rigorous validation strategies.
- Develop and optimize state-space models, Equivalent Circuit Models (ECM), and other simulation models for BMS functionalities.
- Design architectures that support modern EV features, including Over-The-Air (OTA) firmware updates and cloud-based battery diagnostics.
Advanced Algorithm Engineering:
- Design, implement, and validate complex battery state estimation algorithms, including State of Charge (SoC), State of Health (SoH), State of Power (SoP), and State of Energy (SoE) using techniques like Extended/Unscented Kalman Filters (EKF/UKF).
- Develop highly efficient logic for thermal management, active/passive cell balancing, and advanced fault detection.
Battery Technology & Validation:
- Leverage deep knowledge of cell chemistries (LFP, NMC, LTO) to optimize BMS performance, safety, and lifespan.
- Define comprehensive battery testing protocols, including hardware-in-the-loop (HIL) and software-in-the-loop (SIL) testing.
- Analyse real-world and test-bench data to tune BMS algorithms and mitigate degradation and failure modes.
Technical Leadership & Cross-Functional Collaboration:
- Provide expert mentorship and technical guidance to the BMS software development team.
- Act as the primary technical authority for resolving complex design roadblocks.
- Collaborate seamlessly with hardware, systems engineering, and validation teams to ensure flawless BMS integration.
- Code Optimization & Advanced Debugging: Proactively identify performance bottlenecks and bugs. Perform advanced code debugging and root-cause analysis to ensure highly reliable internal software ecosystems.
- System Integration: Integrate standalone tools with existing enterprise software, CI/CD pipelines, and automotive hardware-in-the-loop (HIL) or software-in-the-loop (SIL) testing environments.
- Standard Compliance: Ensure all internal software solutions and automated tools adhere to strict automotive industry standards (e.g., ISO 26262, ASPICE, or MISRA guidelines where applicable).
- Cross-Functional Collaboration: Work closely with vehicle systems engineers, QA teams, and embedded software developers to gather requirements and translate them into efficient software solutions.
- Documentation & Best Practices: Maintain clear, comprehensive documentation for all developed tools. Champion clean code principles, code reviews, and software development best practices within the team.
Qualification:
- Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Embedded Systems, or a related field.
- Experience: 10+ years of hands-on experience in architecting and developing battery management systems for automotive or industrial applications.
- Software & Modelling: Demonstrated mastery of embedded C/C++, Python, and Model-Based Design (MBD) tools such as MATLAB/Simulink.
- Functional Safety: Strong working knowledge of automotive safety standards, particularly ISO 26262 (ASIL B to ASIL D) compliance for BMS.
- Algorithms: Extensive, proven experience in developing and tuning battery estimation algorithms (SoC, SoH, SoP) and control logic.
- Protocols: Deep familiarity with automotive and hardware communication protocols, including CAN, LIN, SPI, and I2C
- Testing: Hands-on experience with HIL/SIL testing environments and battery cycle data analysis.
- Leadership: Excellent problem-solving capabilities with a track record of successfully mentoring technical teams.
Good to Have :
- Direct experience developing BMS specifically for the 2-wheeler and 3-wheeler EV markets.
- Familiarity with AUTOSAR architecture.
- Knowledge of emerging battery technologies (e.g., solid-state batteries, sodium-ion).
